Implicit  implementation  of  the  crossover  function  within  a  twisted-pair  cable,  or  at  a 
wiring panel, while not expressly forbidden, is beyond the scope of this standard.

A.2 10/100Mbps, 10/100Base-TX

When connecting your 10/100Mbps Ethernet Switch to another switch, a bridge or a hub, 
a straight or crossover cable is necessary. Each port of the Switch supports auto-MDI/
MDI-X detection. That means you can directly connect the Switch to any Ethernet devices 
without  making a crossover cable. The following  table  and diagram show  the standard 
RJ-45 receptacle/ connector and their pin assignments:
